To all whom concern:

Be it known that I, WARREN A. PATTER- soN', a citizen of the United States, residing at Dallas, inthe county of Dallas and State of Texas, have invented certain new and useful Improvements in Dis ntegratmg-Machines, of which the followlng 1s a speclfications, I

This invention. relates more particularly to disintegratin, machines for fibrous Lina-- terial.. Y H

The particular feature of the inventionv is to provide means "for bodily revolving a massof fibrous material over a disintegrating member whereby a shearing action. is

' had and the material disintegrated. In car-.

rying out the invention it is proposed to provide a receptacle having shearmgor disintegrating members and :m'eansfor bodily moving the mass of fibrous material across I said members whereby thei'material, is .disintegrated together with means for collecting disintegrated matter andi means. for

. feeding the same to th receptacle- In a more specific embodiment of the vention a disintegratingibottom or grate isv disposed in a support having'lateral extensions above saidgrate. One of the features is to fo m a grate of a plurality of l0-ngi-- tudinal bars, rectangular. in cross section and presenting sharp longitudinal edges. These bars have different dimensions so that some of them project above the others into the "path of the revolving mass of fibrous material. It is alsointended to make these bars reversibleso that when the edges of one side are dull the bars may be inverted and sharp edges presented. The mass of fibrous material is revolved by a beater member and after the edges of the bars presented to the mass of fibrous material become dull the direction of revolution of the heater is reversed Whereby the other edges are pre sented. To facilitate this a reversible hood with a feed hopper at one side is mounted on the support and coversthe heater and grate. The material is fed in the direction of the revolution of the beater and by removing the hood and reversing the same the feed of the material may be reversed in accordance with the reverse revolution of the beater. The hood is made to cover the lateral extensions of the support sov that any foreign hard substance thrown out by cen- Specification of Letters Patent.

Fig. 14 is of one end of the machine, and L Fig- 5'is a sectional detail of one'of the ba s- I V In the drawings the numeral 1 designates Fig. 3 is atransverse verticalsectionall a longitudinalv sectional detail a supporting trame which is rmountedfon standards 2. arcuate' grate'or bottom 7 l 3 is suspended within the frame-and has its ends closed, bysheet metal panels 4:- The I grate depends into. a hopper--5 suspended from the under side of the frame and terminating-in a;;- discharge collar 6. The grate is composed of a plurality of transverse arcuatestraps or hangers 7 one. disposed at each end and' another at the center. These hangers havetheir upper :ends secured to the'mner faces of the side members of the frame 1. Longitudinal shearing or disintegratingbars' 8 and 9 respectively are lfastened' on the hangers by: bolts 10 having 7 their heads countersunk inseats 11 ,inthe bars.- These barsare" rectangular, in cross section, have sharp longitudinal edges and the bars 9 have a greater dimension than the bars 8 so as to project above the latter as is best shown in Fig. 3. It is desirable to arrange the bars 8 and 9 in alternate relation, but the disposition of the latter may be varied. By virtue of some of the bars 9 projecting above the other bars 8, it will be manifest that the bars 9 will be made to do the rougher work, while after being re duced in size by cooperation between the beater and the bars 9 some of the material will lodge between the bars 9 to be acted upon and further reduced by cooperation between the beater and the bars 8. The sharp longitudinal edges of the bars, which of course are spaced apart, act as shearing edges when the mass of fibrous material is moved transversely of the same and by Ihavding some of the bars pro ecting above the yondthe frame at one end and carries a driving pulley 1 1. The beater shaft is provided With radial fingers 'or beater members disposed on .quadrants in a staggered relation. The members 15 have suohlength as same,

; a r theframe 1 at the outer edgebfthe same I 7 11 provide upsta'nding flanges 16 Which act as guards to prevent lateral displacenient and a semioircular hood 17 disposedonthefi'aine 2551 and provided With handles 18 by Whiclfit to-pass over the grate inproxi-m'ityto the said grate beingin concentric'relationvvith' theshaft 13f Alongeach side of maybe liftedfoif. one'side the hood is v provided. With an upstanding hopper =19.

Asshow'nj' in Fig. 31 the hopper isat-the ,left hand side of themachine and the-beater is revolving toward the -le'ft,#thus fibrous ma} terial' such as ;cotton hulls, leavesand'stems' when? deposited 'kin the hopper will be fed into the machine in the direction {toward Which the beater is revolving.

.Th'ejfibrous matter fed intofthe'hood 17 carried around by the beater' arms 15 and v revolvedin amass over thefgrateB. The

shearing edges of .the'bars Sand 9 cut or disintegrate said material 'so-that' f it falls between said bars-into the hopper 5 and is discharged through the collar .6 'from which polnt it maybe suitably handled. The spacingvo f the bars'rs and 9 may be varied and good results are had byspacing those bars at thecenter farther apart than those at the side. It Willbeseen that the hood incloses theupper faces or surfaces of the side members of the frame 1 whereby ledges are provided "along each "side of the 'machine. Shouldh'ard material such as metal-or-stone be fed into the machine the same Will be thrown out by the centrifugal action of the beater against the curved Wall'of the hood and thus guided down on to said ledges Where such materials Will rest until removed. This prevents injury to the machine.

It Will be seen that with the beater revolv ing toward the left as indicated in Fig. 3,.

only one edge of each bar Will b'eutilized andafter a'certain period of operation said edges Wlll ibecome dull. f In order to utilize the other edgesithe beater is revolved in the opposite direction, and to facilitate proper feeding the hood 17 is'removed andrever-sed so that'the hopper 19 is disposed on the oppe'sitelsid'e Will be obvious.

A machine of this character is economical and substantial. r In. grinding certain fibrous materials a maehine of considerable strength is roqui'r edand I have found thefpresent structure to Wit-hstand hard usage and to efficiently disintegrate \the materialand furs ther to have great capacity.

The foregoing description and illustration clearly; expressthe invention, but it is understood that said "illustration is merely an exemplificati'on' andthe inventionmay be carriedfbut in various otherwways.

What I claim; is,

A grate for use 1n a disintegrating machine andin conjunction "vvith. abeater rev- :1 oluble at right. angles 9 to the-length of the grate, comprising alternate longitudinal.

bars of-difli'erent heights, spaced throughout their "lengths, vvith "each bar .ofea single piece of material and entirely'sep'arated from theadjacent bar, and-each'bar having exposed shearing edges at its :upper'corners.
